US Sees a Big Jump in Nausea Cases Among Frequent Marijuana Users in the Hospital
Federal researchers said the new billing code exposed nearly 200,000 syndrome-related emergency visits and helped reveal higher rates among young people and women.
Last week, the CDC released a report showing a 16% rise in hospital emergency room diagnoses for cannabis hyperemesis syndrome from last October through May. Researchers analyzed data from about 7,500 healthcare facilities across the country.
A new diagnosis code implemented last fall is largely responsible for the increase, providing a more accurate picture of a previously underrecognized problem. Before this, tracking the syndrome required combining separate diagnostic codes for nausea and cannabis use.
The largest increases occurred in people aged 15 to 24, with significant rises in teenage girls, women, Black Americans, and American Indian and Alaska Natives. These demographic patterns prompted calls for increased awareness in younger populations.
"Was actually one of the surprising findings for us," said CDC's Alana Vivolo-Kantor, the study's first author. Researchers initially questioned how young people could exhibit chronic marijuana use patterns.
Past research estimates 2.75 million Americans suffer from the condition annually, with hospital visits rising alongside recreational marijuana use. The report calls for more research into how high-potency THC products affect younger populations.
